WINDLASS.

SPECIFICATION forming part of Letters Patent No. 631,653, dated August22, 1899.

Application filed May 16, 1899. Serial No. 716,999. (No model.)

To all 1.071,0771/ t 77mm/ concern:

v Be it known that I, 'GEORGE WASHINGTON MORGAN, of Dawson, NorthwestTerritory, Dominion of Canada, have invented a new and ImprovedlVindlass, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in windlasses by which thewindlass is made of a more simple and light construction than ordinarilyand by which also the wi'ndlass-crank is automatically freed from thedrum if the latter suddenly starts backward, whereby the accidents whichare of frequent occurrence from this cause are prevented.

My invention comprises the novel features which will be hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal elevation, partially in section, of mydevice. Fig. 2 is an end elevation thereof. Fig. 3 is a sectional planshowing the roller-bearing for the windlass-drum. Fig. 4 is a sectionalelevation of a clutch connection between the crank and the drum-shaft.Fig. 5 is a plan of the clutch connection for the crank and aclutch-conF trolling wheel partly in section.

In using windlasses about mines and similar places it often happens thatthe crankhandle will slip out of the operators hands or in other waysthe windlass Will suddenlyl be freed, so that the weight which issuspended thereon will revolve it rapidly backward, in which case thecrank, if it should strike the operator, is liable to cause very seriousdamage.

The principal object of my invention has been to connect the crank withthe drum of the windlass in such manner that if it is suddenly freedfrom any cause the crank will be released from the drum of the windlass,and accidents due to this cause may be averted.

Another object has been to make the essential parts of the windlasswhich cannot be provided near where the windlass is to be used of suchshape and construction that they may be light and easily transported.

The windlass as herein shown is designed to be supported upon the upperends of two -posts A, which have notches a formed in opposite sides andadapted to receive the nuts L2, which are placed upon the lower ends ofthe f rame-bars L. lOne of these posts is placed at each side of theshaft-opening, and the frame-bars L, which are of an inverted-U- shapeand made of round iron, have their lower ends inserted through holesbored in the upper end of the posts and terminating in the notches a.The lower portions of the frame-bars L are threaded so as to receivenuts L and L2, which are placed respectively at the upper end of thepost and in the notches a. Upon the upper ends of the posts are placedthe lower halves F of a casing which contains the rollerebearings forthe windlassshaft. lVithin this casing are placed two shafts carrying,respectively, the double rollu ers M and the single roller M', which areadapted to support the shaft E in the valley between the upper portionsof said adjacent rollers. This bearing is in many respects similar tothe bearing often used for grindstones. The upper casing F is placedabove the rollers and has holes adapted to receive the shaft E. Theupper casingsection Fhas slight flanges at its edges adapted to retainthe strap G, which is made of flat bar-iron and passes about the twocasing-sections and is held down upon the post A by means of the nuts L.

A brace-bar Il, which is constructed of flat bar-iron, is bent at eachend, so as to form an open clip H', the ends of said clips beingprovided with holes adapted to receive the two vertical members of theframe-rod L. The central portion of this bar I-I is bent downwardly andhas atshort section H2 bearing upon the strap G, which is above thejournal-casing FC The length of the vertical members of the frame-bars Lis adjusted by the nuts Ll L2, so that the bends in their upper portionsengage with the extreme ends of the brace-bars H, and thus hold themfirmly. The opening provided by the clip H formed in each end of eachbrace-bar is adapted to receive an end of a longitudinal bar K, whichextends from one of the posts across to the opposite one, thusconnecting them and holding them firmly together by the clamping actionof said clips. The parts described which form the frame of the Windlassmay all be .held

-together and drawn up snugly by the nuts L and L2 upon the lower endsof the framebar L.

Upon one of the bars K which extends longitudinally of the windlass ismounted a dog J, which engages ratchet-teeth d, formed upon a cap orband which surrounds one end of the windlass, thus preventing its flyingbackward This pawl is operated to release the windlass by means of alever J,which is pivoted upon one of the longitudinal bars K. The\\'indlassdrum is formed of a round log D or in any other convenientmanner and may be made of a length to correspond with the requirementsof each particular case. At one end it is provided with a band D2, whichprevents the log from splitting, said band being preferably providedwith a flange, which will retain the rope in place. The other end of thedrum is placed within a cap D', which consists of a plate having a ringor flange divided into two sections, one of which is provided with theratchetteeth d, before mentioned, and the other section d renderedsmooth and adapted to receive a friction brake-band l. This cap islirmlysecured to the windlass-drum by means of lag bolts or screws d2 orin any other convenient manner.

The cap D' has a shaft E extending therefrom and resting upon therollers M and M', forming the bearing at this end of the windlass. Thisshaft extends through said bearing, and on the projected portion a bossNis secured thereto, forming one half of a toothed clutch, the teeth Nformed on the end face of which are sloping in one direction, so thatwhen turned in direction of the slope of the teeth it will slide uponthe other half of the clutch without rotating it, but will engage itfirmly when turned in the opposite direction. The other half of theclutch is formed upon the hub of the crank-arm O and is provided withteeth O similar to the teeth N and meshing therewith. This crank-arm ismounted loosely upon the shaft E and is engaged with the shaft to turnit by being forced toward the boss N. The hub of the crankarm is hollow,as shown in Fig. l, and within this hollow is placed a spirally-coiled.spring i, which is so adjusted as to normally hold the two parts of theclutch separated. Outside of the crank-arm O is a wheel l), which ismounted loosely upon the shaft, but is prevented froln slidinglongitudinally upon the shaft beyond a certain point by means of a nut pplaced upon the end of the shaft.

The outer face of the hub of the crank-arm has inclined surfaces O2,forming cams which are adapted to be engaged by the ends of setscrews P,which pass through the wheel l. These surfaces are inclined in the sainedirection as the teeth upon the opposite face of the hub. By reason ofthis construction if the wheel P is turned so that the ends of thesetscrew lie at the bottom of the inclines the spring R will force thecrank-arm away from the boss N, and thus release it from thewindlass-drum, while if the wheel l be turned so as to cause the ends ofthe set-screws to ride upward on the inclines the crank-arm will beforced toward the boss N and the teeth O' and N/ engaged so as to lockthe crank-arm to the windlass. By reason of the relative inclination ofthe surfaces Ogand the teeth Oif the wiudlass is given a sudden startbackward the inertia of the wheel l will cause it to lag behind themotion of the crank-arm and the ends of the set-screws P will slide downthe inclines, thus permitting the spring Rto disconnect ihe crank-armfrom the windlassshaft. The windlass will then run down without thecrank being turned by it, and many accidents which are caused bysuchaction of ordinary windlasses will be prevented. A bar Q is shown asextending from the crankarm over the face of the wheel P, so that thesame is protected against disturbance while in use. A frictionband-brake is provided by connecting one end of the iron band I to oneof the longitudinal bars K and carrying it about the smooth portion ofthe cap D. At its free end it is provided with a handle l2, by means ofwhich it may be operated.

The form of frame herein described, it will be seen, is very light. Atleast that portion which must be transported to the point where thewindlass is to be used is very light. It is possible in most locationsto find wood from which the wooden portions of the windlass may beconstructed.

The end of the windlass-drum D which is opposite the crank is providedwith a gudgeon E, which may be inserted in its end and l'orm the journalupon which it turns. The end Ol ot' the crank has a handle S thereon,adjustable to accommodate people of different sizes. The opening in theeye Slot' the handle and the end Oi of the crank are not completelycircular in cross-section, so that the handle will not turn about thecrank, and the handle may be secured in any position by a set-screw S'.By this means the length ol' handle may be readily adjusted to suitpersons of different stature, and thus contribute much to the comfort ofthe operator and cnable him to accomplish more in a given time.

lla-ving thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A windlass, having a crank mounted loosely onits shaft and provided with a face ratchet or clutch connection with thedrum, means acting to separate the parts of said clutch whenunrestrained, the outer face ol' the crank-hub having cain-inclinescorresponding in direction of slope with the teeth upon its inner face,and a wheel journalcd upon the outer end of the shaft and havingprojections adapted to engage said cam-inclines, substantially asdescribed.
